I have a slight problem there mo, my lfs doesn't specify male or female. I'd prefer an all male group however, my inlays have 2 of the red wag platies. No breeding has happened, they also have 4 mollies and 4 balloon mollies and theyve had no fry. I'm thinking the lfs only sell one sex full stop. Although despite me telling them mollies are brackish they won't put salt on so I guess they might not be breeding because of not having ideal conditions?
